在第三单元教学中我高效引入单元话题，激活学生已有图式

呈现地图示意图，激活图式

教师在上课前给学生呈现学生画的地图，学生感觉很是亲切，为本课学习地图谈论指路问路和谈论地点埋下伏笔。

这是文本呈现的地图，教师利用图片呈现杨林到达苏海的家的路线。

She takes the ... to Suhai's home.

First, she gets on the metro at ...Station.

Next, she ...s at...Station.

Then, she comes out ...

She is on ... Street.

Then, she walks along ...and turns ...at the ...

There's a ...on the street.

Su Hai’s new home is ...the bookshop.

这是练习呈现的map,让学生意识到地点，做的事，以及线路图。

I want to see the doctor.

I want to go to the hospital.

The hospital is on B___ Street.

教师聚类呈现表示生病的单词。激发学生的已有词汇并拓展一些词汇如toothache等，为第四单元学习seeing the doctor埋下伏笔。
